Abstract: 1355936 Electronic timepieces SUWA SEIKOSHA KK 7 Feb 1972 [18 Feb 1971] 5578/72 Heading G3T An electronic timepiece with digital display (e.g. liquid crystal or light emitting means) functions both to indicate the time of day and as a stop watch to indicate a time interval t 2 -t 1 . A time standard pulse generator 1 Fig.1 (e.g. quartz crystal, tuning fork or atomic particle) output is frequency divided at 2, 3, the divider 3 dividing down to signals at the smallest time interval to be displayed e.g. seconds and the divider 2 having an output f 1  of several KHz if the time display is to read down to 1/1000 sec (for stop watch operation). TIME OF DAY INDICATING. 1Hz pulses from divider 3 are fed to counters 4 to 9 which produce respective outputs for the control of the secs, tens of secs, mins, tens of mins, hours, tens of hours display indication. For a 24 hour clock the counter 9 would be a 1/3 divider circuit for indicating 0, 1 and 2 in the tens column of the hours display. With a switch WC in the 'W' position, AND gates 20 are opened to pass the contents of counters 4 to 9 to OR gates 22 and thence to signal distributors 23 to 28 to supply operating signals to appropriate elements of seven-element numeric display devices 29-34, to indicate time of day. TIME INTERVAL INDICATING (STOP WATCH). The output f 1  of divider 2 is fed to a divider 10 which divides f 1  into signals of for example 1/10 sec or 1/100 sec or 1/1000 sec period depending upon degree of precision required. The output of 10 (say at 1/100 sec period) is fed to counters 11 to 16 which produce respectively outputs for the control of 1/100 sec, 1/10 sec, 1 sec, 10 secs, 1 min, 10 mins. Switch WC is moved to the 'C' position so that the AND gates 20 are closed and AND gates 21 opened. A reset button (not shown) is pressed and a reset signal at R resets divider 10 and counters 11-16 to zero and the display will indicate zero. To start timing a push switch (not shown) connected at S is pressed at instant t 1  and a flip-flop 17 changes state so that divider 10 commences to transmit 1/100 sec signals and counters 11-16 commence counting and produce on the display the appropriate count. When the switch at S is pressed a second time at an instant t 2  the flip-flop 17 is reset, the divider 10 stops and likewise the counters 11-16, and a time interval t 2 -t 1  will be displayed on the same time display devices as were used for time of day indication. If the time interval range to be measured is wide e.g. 1/100 sec to 1 hour, a separate display array may be provided. An arrangement whereby more than one time interval at a time can be measured by one timepiece, is described with reference to Fig. 2 (not shown). Dividers, logic circuits &c. may be M.O.S. integrated circuits.

Title: Method and apparatus for preparing a solution of a single constituent from a solution containing a plurality of dissolved substances
IPC: C05C5/00
Filed: 1948-02-25
Abstract: A continuous process for obtaining a solution of a single component having a negative heat of solution, wherein a compound solution containing said component and others is evaporated under sub-atmospheric pressure so that crystals of the required component are formed; both the vapours and the crystals being withdrawn from the evaporator and introduced into a direct-contact condenser in which a solution of said single component is circulating, and from which <PICT:0655084/III/1> part of said circulating solution is continuously withdrawn.  The heat of condensation of the vapours is thus utilized for dissolving the crystals.  The solution obtained by digesting raw phosphate with dilute nitric acid is introduced through pipe 3 into a circulating system comprising pump 4, evaporator 1, and crystallizer 2.  A 50 per cent solution of calcium nitrate is circulated by pump 7 through cooler 8, direct-contact condenser 5, and reservoir 6.  The entire system is evacuated by steam-ejector 9. The evaporator 1 is maintained at 4.3 mm. whereby the digestion-liquor evaporates at 15 DEG  C. and deposits crystals of calcium nitrate; these crystals are separated from mother-liquor in centrifuge 11 and then introduced in reservoir 6.  The vapours from the evaporator pass to the condenser through pipe 10.  The temperature of the solution circulating in the condenser is maintained at 3.2 DEG  C. by cooler 8; and the solution is maintained at the required concentration by adding water through pipe 14. Part of the solution is continuously withdrawn through line 15.

Title: Improvements relating to clutch-operating apparatus on motor vehicles
IPC: B60K23/02
Filed: 1958-02-21
Abstract: 834,865. Gearing for stopping and starting machinery. DAIMLER-BENZ A.G. Feb. 21, 1958 [Feb. 28, 1957], No. 5717/58. Class 80 (2). [Also in Group XXVIII] A vacuum pump 14 of the diaphragm type is used to energize a servomotor 7 disengaging a mechanical clutch between an engine-driven hydrodynamic coupling and a change-speed gear 2 in a motor car. Disengagement of the clutch is effected by manual operation of a ratio-shift lever 9 controlling an electromagnetic multiple valve assembly 8, also under the control of the car throttle pedal 10 and the clutch actuating lever 5. The initial clutch re-engaging movement of the actuating lever 5 conditions the valve 8 controlled thereby to admit air rapidly to the servomotor 7 until the clutch is just engaging. During further movement of clutch actuating lever 5, the associated valve admits less air, to give a cushioned completion of clutch engagement. If, however, the throttle pedal 10 is depressed, another of the valves 8 is opened and air is admitted quickly to the servomotor 7 to complete clutch engagement rapidly. The vacuum pump comprises an engine-driven shaft 20 rotating a cam 21 to reciprocate a first rod 19 abutting a second rod 18 biased by a spring 22 into engagement therewith, the second rod being fast with a diaphragm 17 movable in a pumping space 16. The diaphragm draws air in through a pipe 23 and a one-way valve 24 from a vacuum reservoir 12, and expels it through a second one-way valve 25. As the pressure is a vacuum reservoir 12 falls, the reaction upon the diaphragm 17 increases, so that the spring 22 is unable to complete the strokes of the second rod 18. Accordingly, movement of the diaphragm 17 gradually lessens and ultimately ceases. As a modification, the diaphragm pump may be combined with the fuel pump of the car engine.
